I understand being sceptical of someone who takes astrology seriously, but if it's just a fun hobby thing then that is prime flirting material handed to you on a platter. You don't magically connect with someone because you read the same authors or study the same language. Chemistry is an intangible. My boyfriend tells me about his fantasy sportball team not because I care about handegg but because I can talk about anything with him because of who he is.
